Give a Rule for the Piecewise-Defined Function $f ( x ) = \left\{ \begin{array} { l l } 2 & \text { if } x \leq - 3 \\ 4 & \text { if } x > 4 \end{array} \right.$

Give a rule for the piecewise-defined function. Then give the domain and range.

A) $f ( x ) = \left\{ \begin{array} { l l } 2 & \text { if } x \leq - 3 \\ 4 & \text { if } x > 4 \end{array} \right.$ ; Domain: $[ 2,4 \}$ , Range: $( * - 3 ] \cup ( 4 , \infty )$
B) $f ( x ) = \left\{ \begin{array} { l l } 2 & \text { if } x < - 3 \\ 4 & \text { if } x \geq 4 \end{array} ; \right.$ Domain: $\{ 2,4 \}$ , Range: $( \infty - 3 ) \cup [ 4 , \infty )$
C) $f ( x ) = \left\{ \begin{array} { l l } 2 & \text { if } x \leq - 3 \\ 4 & \text { if } x > 4 \end{array} ; \right.$ Domain: $( \infty - 3 ] \cup ( 4 , \infty )$ , Range: $\{ 2,4 \}$
D) $f ( x ) = \left\{ \begin{array} { l l } 2 & \text { if } x < - 3 \\ 4 & \text { if } x \geq 4 \end{array} \right.$ ; Domain: $( \infty - 3 ) \cup [ 4 , \infty )$ , Range: $\{ 2,4 \}$
